There is a line measuring instrument, how to find the seat in the room corresponding to the location of patch panels
I also encountered similar problems at both ends after adding a corresponding label it
Generally, it is 16mm2 if it is a bridge trunk as a grounding line. On the repeated grounding and your length, the general recommended about 30m repeated ground.
Indoor wiring with wire trunks, it should be such a construction sequence: 1. Let the electrician first all the switch box all the lines put away. 2. Then, call the painter to make all the wall brush gray. 3. Call the electrician to secure the trunking on the wall and enclose the wire in the trough. 4. Next called the paint on the latex paint. 5. After the end of the painter, and finally called the electrical installation of household appliances and lighting. Why should this be done? I explain to you the reasons: paint workers and electrician cross construction, is to both the construction does not conflict, interference. Can better grasp the construction quality of both, but also improve the efficiency.
